Abstract

The modifications in corrosion resistance and local surface modifications caused by the colonization of Pseudoalteromonas NCIMB 2021 bacteria on mild steel in artificial seawater were investigated using electrochemical techniques, Scanning Electron Microscopy and Time-of-Flight Secondary Ion Mass Spectrometry. A dual role of these bacteria on corrosion resistance was observed and characterized. While an improvement in corrosion resistance was obtained in the presence of the bacteria, the colonized surface is locally modified and once the bacteria are removed, the previously colonized areas are exposed, leading to enhanced localized corrosion.

海洋细菌假互生单胞菌NCIMB 2021对低碳钢在人工海水中腐蚀的双重作用

采用电化学技术、扫描电镜和飞行时间二次离子质谱技术研究了NCIMB 2021假互变单胞菌在人工海水中对低碳钢的耐蚀性和局部表面修饰的影响。观察并表征了这些细菌在耐腐蚀方面的双重作用。虽然在细菌存在的情况下获得了耐腐蚀性的提高，但定植表面会局部改变，一旦细菌被去除，先前定植的区域就会暴露出来，导致局部腐蚀增强。

期刊介绍： Corrosion occurrence and its practical control encompass a vast array of scientific knowledge. Corrosion Science endeavors to serve as the conduit for the exchange of ideas, developments, and research across all facets of this field, encompassing both metallic and non-metallic corrosion. The scope of this international journal is broad and inclusive. Published papers span from highly theoretical inquiries to essentially practical applications, covering diverse areas such as high-temperature oxidation, passivity, anodic oxidation, biochemical corrosion, stress corrosion cracking, and corrosion control mechanisms and methodologies. This journal publishes original papers and critical reviews across the spectrum of pure and applied corrosion, material degradation, and surface science and engineering. It serves as a crucial link connecting metallurgists, materials scientists, and researchers investigating corrosion and degradation phenomena. Join us in advancing knowledge and understanding in the vital field of corrosion science.
